Answer: -
5 : 1 : 3
Explanation: -
Mass of CO₂ = 2.2 g
Molar mass of CO₂ = 44 g / mol
Number of moles of CO₂ = 
= 
= 0.05 mol
Number of atoms of nitrogen = 6.02 x 10²¹
Number of moles of nitrogen = 
= 
= 0.01 mol
0.03 gram atom of sulphur means 0.03 moles of sulphur.
Thus the mole ratio of CO₂ : N : S = 0.05 : 0.01 : 0.03
= 5 : 1 : 3
Answer:
λ = 0.002 nm
The given photon is either x-ray or gamma ray because the range of x-ray and gamma ray is 1 nm-0.1 pm.
Explanation:
Given data:
Energy of photon = 1.10 × 10⁻¹³ J.
Wavelength of photon = ?
Solution:
Formula:
E = h.c / λ
λ = h. c / E
λ = 6.626 × 10⁻³⁴ j. s × 3×10⁸ m/s / 1.10 × 10⁻¹³ J.
λ = 19.878 × 10⁻²⁶m / 1.10 × 10⁻¹³ J
λ = 18.071 × 10⁻¹³ m
λ = 18.071 × 10⁻¹³ × 10⁹
λ = 18.071 × 10⁻⁴ nm
λ = 0.002 nm
The given photon is either x-ray or gamma ray because the range of x-ray and gamma ray is 1 nm-0.1 pm.
Answer:
Here
Explanation:
This is an acid-base reaction (neutralization): CaCO3 is a base, HCl is an acid.
Answer:
5
Explanation:
Carbon tetrachloride has molecular formula as CCl4 , so from this it is evident that there are 4 atoms of Chlorine & 1 atom of carbon is present, in total 5 molecules are present in carbon tetra
